Hi, I have just joined and would like to introduce myself as Martyn .I have just bought a pretty old Powabyke (shopper ?). I bought it with a couple of obvious faults , one is the electrics cut out when going over a bump or when the ignition key is wiggled in the lock. The second is a pretty dodgy bottom bracket which seems to have been welded at the top of the peddle arm and there is also too much movement in the bracket, so I am guessing I need to cut the welded arm off and fit a new assembly including a new peddle arm .The chain side is bolted on and seems to be ok. Can anybody please advice me on these two issues.My first thought on the cutting out if the electrics was either loose or corroded battery terminals or a worn ignition , but I cannot work out how the battery is accessed , if that is possible . Thank you in anticipation for your help ,Martyn
